Background Patient and Public Involvement (PPI) is the active partnership between researchers, patients and laypeople in the process of creating research. PPI in stroke aphasia research aims to ensure equal opportunities for informed decision-making and guarantee democratic representation of patient partners within the research team. Yet, little is known about the factors that hinder and/or promote the autonomous involvement of people with aphasia in stroke and aphasia PPI projects. This study aimed to explore the views and perspectives of people who live with chronic stroke, with and without aphasia, with experience in research prior to stroke, on their potential involvement as research partners. Methods The research team included a PPI partner with chronic stroke-induced aphasia. Semi-structured interviews were conducted online with people with chronic stroke (n = 8), four with aphasia and four without. Interviews were subject to thematic analysis. Results Inductive thematic analysis generated four themes: (1) the kinds of Restrictions that make involvement in research difficult, (2) the preferred levels and ways of Involvement during the research process, (3) the Support required for active and collaborative involvement, and (4) the Impact of their involvement and how it benefits the study’s outcomes. Conclusion People experiencing chronic stroke and aphasia are willing to be involved as PPI partners if the research team provides the necessary support. Recommendations for researchers to consider before commencing co-produced research with people with stroke and aphasia are provided.

Background Evidence‐based assessments for people with aphasia (PWA) in Greek are predominantly impairment based. Functional communication (FC) is usually underreported and neglected by clinicians. This study explores the adaptation and psychometric testing of the Greek (GR) version of The Scenario Test. The test assesses the everyday FC of PWA in an interactive multimodal communication setting. Aims To determine the reliability and validity of The Scenario Test‐GR and discuss its clinical value. Methods & Procedures The Scenario Test‐GR was administered to 54 people with chronic stroke (6+ months post‐stroke): 32 PWA and 22 stroke survivors without aphasia. Participants were recruited from Greece and Cyprus. All measures were administered in an interview format. Standard psychometric criteria were applied to evaluate reliability (internal consistency, test–retest, and interrater reliability) and validity (construct and known‐groups validity) of The Scenario Test‐GR. Outcomes & Results The Scenario Test‐GR shows high levels of reliability and validity. High scores of internal consistency (Cronbach's α = 0.95), test–retest reliability (intra‐class coefficients (ICC) = 0.99), and interrater reliability (ICC = 0.99) were found. Interrater agreement in scores on individual items ranged from good to excellent levels of agreement. Correlations with a tool measuring language function in aphasia, a measure of FC, two instruments examining the psychosocial impact of aphasia and a tool measuring non‐verbal cognitive skills revealed good convergent validity (all ps < 0.05). Results showed good known‐groups validity (Mann–Whitney U = 96.5, p < 0.001), with significantly higher scores for participants without aphasia compared with those with aphasia. Conclusions & Implications The psychometric qualities of The Scenario Test‐GR support the reliability and validity of the tool for the assessment of FC in Greek‐speaking PWA. The test can be used to assess multimodal FC, promote aphasia rehabilitation goal‐setting at the activity and participation levels, and be used as an outcome measure of everyday communication abilities.

The impact of aphasia on the everyday life of Greek-speaking people with aphasia (PWA) is often underestimated by rehabilitation clinicians. This study explores the adaptation and psychometric properties of the Greek (GR) version of The Aphasia Impact Questionnaire-21 (AIQ-21-GR) to address this issue. The aim of this study is to determine the reliability and validity of the Greek version of the AIQ-21. The AIQ-21-GR was administered to 69 stroke survivors, 47 with aphasia and 22 without aphasia. The data were analyzed to determine reliability and validity. Content validity was based on the Consensus-based Standards for the selection of health Measurement Instruments guidelines. The AIQ-21-GR shows high levels of reliability and validity. The results confirmed high scores of internal consistency (Cronbach’s α = 0.91) and indicated good known—groups validity (Mann–Whitney U = 202, p < 001). Content validity achieved high scores with an overall median score of 4 [Q25 = 4, Q75 = 5]. The psychometric properties of the AIQ-21-GR support the reliability and validity of the tool for investigating the impact of aphasia on the quality of life of Greek-speaking PWA. The AIQ-21-GR can be used for setting functional goals in collaboration with PWA and as a patient reported outcome measure for functional communication training.

Episodic memory decline is the prominent neuropsychological feature of typical Alzheimer's Disease (AD), for which current treatments have a limited clinical response. Recently, gamma entrainment therapy has been used as a non-invasive treatment in AD, providing evidence that it may have the potential to alleviate brain pathology and improve cognitive function in AD patients. At the same time, the precuneus (PC) has been recognized as a key area involved in AD related memory deficits and as a key node of the Default Mode Network. This study aimed to investigate the effectiveness of a 40 Hz Transcranial Magnetic Stimulation (TMS) intervention, delivered bilaterally to the precuneus for 10 days, in improving the patients' episodic memory performance. Secondary outcome variables investigated included general cognitive function, semantic and spatial memory, as well as attention and executive function. A concurrent multiple baseline design across five cases was employed. Four patients completed the study. Visual analysis combined with effect size indices were used to evaluate changes across phases. An increase in the average level of immediate recalled words was observed in three out of four patients. Effect size indices indicated significant improvement of attention skills in two patients. No treatment effect was observed for semantic and visual memory, or for executive function. An
